Are you ready to truly test your knowledge of SQL and Relational Database Design?

This comprehensive practice test course is designed to solidify your understanding and prepare you for certification exams or technical interviews.

Course Overview

This course provides multiple full-length practice exams simulating real-world technical assessments. You will be challenged on both theoretical concepts of database design and practical application of complex SQL syntax. We cover everything from basic SELECT statements to advanced topics like transaction isolation levels and optimization strategies.Each practice test is timed to mimic exam conditions, ensuring you build both speed and accuracy. Crucially, every question comes with a detailed explanation, clarifying why the correct answer is right and why the incorrect options are wrong. This process transforms taking tests into a powerful learning experience.

Key Topics Covered

• Data Manipulation Language (DML): Complex Joins (INNER, LEFT, RIGHT, FULL), Subqueries, Aggregate functions, GROUP BY, HAVING.

• Data Definition Language (DDL): Creating tables, defining Constraints (PRIMARY KEY, FOREIGN KEY, CHECK, UNIQUE), and managing indexes.

• Normalization: Identifying and correcting design flaws up to 3rd Normal Form (3NF).

• Advanced Concepts: Transactions, ACID properties, views, stored procedures, and basic performance tuning.
